How to check if Specified Element is present in the Array in Go ?

Answer

To check if a specified element is present in an array in Go, you can use a loop to iterate through the array and check each element.

✐ Examples

1 Check if Element 30 is present in Integer Array

In this example,

We create an integer array named numbers with values 10, 20, 30, 40, 50.
We iterate through the array using a for loop and check each element if it matches the specified element 30.
If the element is found, we set a boolean variable found to true; otherwise, it remains false.

Go Program

package main
import (
    "fmt"
)
func main() {
    numbers := []int{10, 20, 30, 40, 50}
    found := false
    for _, num := range numbers {
        if num == 30 {
            found = true
            break
        }
    }
    fmt.Println("Element 30 is present:", found)
}

Output

Element 30 is present: true

2 Check if Element 'banana' is present in String Array

In this example,

We create a string array named fruits with values 'apple', 'banana', 'cherry'.
We iterate through the array using a for loop and check each element if it matches the specified element 'banana'.
If the element is found, we set a boolean variable found to true; otherwise, it remains false.

Go Program

package main
import (
    "fmt"
)
func main() {
    fruits := []string{"apple", "banana", "cherry"}
    found := false
    for _, fruit := range fruits {
        if fruit == "banana" {
            found = true
            break
        }
    }
    fmt.Println("Element 'banana' is present:", found)
}

Output

Element 'banana' is present: true
